PAPER PEBIOEAEZHG, ma,'m DELIVERY APPAIRATUB.

This invention relates more particularly to improvements in the perforating, euttmg and delivery apparatus for web printing 1113-- chines. and has to do especially with apparatus of this character applicable to machines for printing the leaves for memorandum or counter check books, wherein the original and duplicate leaves are printed upon dill'ercntly colored paper, and therefore, l'mm dill'erent webs running through the machine. \Vhile lhave shown my improved apparatus as adapted for such a machine. I do not. however. confine it to such appli ation. since the features of novelty may be applied-as well tosingleweh machines. and to machines for other purposes.

()ne object of my improvements is to provide an apparatus of this character. \Vltttl'w in the perforating of'the web will be perfonnedafter the. web has passed the printing cylinders. and just before it is cut into sheets and discharged upon th delivery table.

A further object is to provide means whereby the web will be entirely relieved'from tearing strains during the perforating and cutting operations. And a final object is to provide an innu'ovcnn-nt in the delivery mechanism whereby the Shl't'iS'lTlfi) be dolivercd from the cutting: mechanism at a high speed. stacked in packets of the desired number of leaves. and delivered from the stacking and j gging mechanism in proper s quenue as fast as'the packets are completed.

I attain my objects by constructing and arranging the parts of the apparatus in'the manner illustrated in the accompanying drzwings,'in which- Figure 1 represents a plan view of the up pantus, as applied to a two web printing machine; Fig. 2, a side elevation thereof;

Fig. 3, a vertical section on the line a-a in Fig.1; and Fig. 4, a detail showing a sectton through the perforating mechanism.

Like numerals designate like parts in the several views.

The apparatus is mounted between two frame-plates. 1. 1. adapted to be fastened I Specification 6! Letter: Patent. Application no Imunry 22:15:. am 11-. 4121.29.

in any desirable position, and carrying upon i their under sides a delivery table 2, (part. only of which is shown in the drawings).

From the printing cylinders of the machine the web, or webs, of paper will be delivered to feed rolls 3, 4, and 3. 4", from suitable guide rolls, not shown. Where two webs of paper are to be run through the machine. said webs, (see A. ll. Figs. 3.), will be brought into exact. vertical alinement by properly adjusted guide rolls, before entermg the feed rolls. From these feed rolls the webs of paper pam'over aprons 5, and 15. to the perforating cylinders. t3, 7, and 6', 7. These perforating cylinders may be of any desired type. although I have shown in the apparatus a perforating mechanism which I have devised particularly for this work. said mechanism being fully shown and described in a separate application filed of even date herewith and bearing Serial X0. 413,288.

Vithout. going into spe ific details, this perforating mechanism consists of a circum ferentially grooved cylinder 6, a cylinder segment 7, adjustably mounted upon a cylinder tl, and carrying a radially reciprocating perforating blndc J. the teeth on which enter the grooves on cylinder 6; said blade being pro ected from the segment. when in radial alincment with the cylinder 6, by. means of an arm 10 attached to one end of an operating shaft 11, mounted in the segnu'ntrsaid arm being operated at the proper tnomcnt by means of a roller 12. mounted upon a pin at the free end of the arm and engaging a cam surfa e l3. projecting from the inward side of one of the frame-plates I.

.\lotion is imparted to the perforating blade from shaft 11 by nit-an of arm 11. (see Fig. l,)'. fastened tothc shaft at each end of the segment and engaging projections from the ends of the blade. The perforating teeth are. bythis means, inuncdiately disengaged from the web after perforating it. leaving it .free to continue in its line of travel to the cutting mechanism.

From the pcrforators the webs pass along aprons'l l, and 16, over the stationary cutti blade 17, to the apron The blade 17 IS adiistably mounted on a crass bar 18, attached to the journal blocks which carry the cutting cylinder 19. Carried by the cylinder 19 is a cutting blade A central ring 21 fastened on the cylinder acts as to the main frame of the printing machine, a guide to prevent the paper from rising H-.. w v

or bm-lilin as it passes from the stationary miner lilflt e to apron 2'2. TlllS ring is cut away or flattened. at 21, back of the blade,-

to permit the ends of the webs to pass freely 5 over the blade 17 before they pass to the apron 22. While I prefer to use the ring for economy in eonstruction, I may make the cylinder 19 of the full diameter and dispense with the ring.

From the apron 22 the paper passes between rolls 23 and 24, the upper of said rolls being mounted in vertically movable journal boxes '25, in order that the rolls may in; separated during certain periods, as will hereinafter he set forth. The journal boxes 2.: are mounted in guides 26, and are pressed downwardly by springs, the tension of which is regulated by set screws 27. The roll :2?) is raised at the proper periods by means of the bent levers 28, pivoted on the frame-plates at each side and actuated by earns "29 on the shaft of the cutting cylinder.

From the rollsZZl and 24, the severed sheets are delivered upon the inwardly projeeting ledges 30, at the to of the. sides of the packing and jogmg ox; said ledges 30 being set slightly e oser together thanthe width of. the sheets, so that. said sheets will rest momentarily upon the ledges before 30 they are deposited in the jogging box. F or delivering the sheets to the jogger, 1 provide a pair of horizontal vertioall'v recipro eating presser arms 31. said arms being fastened n hrat'kets 3'2, (lumped to a cross bar This cross bar, at each end. is mounted .in blocks 34; attached to the upper ends of vertical rods 33; said rods being mounted to slide in the ends of the frame-plates 1. and having their lower ends engaged and pressed upward by coiled springs Btiqnounted in cylindrical casings 37, (see Fig. 3.).

lock arms 38, mounted upon the oscillating shaft 3! bear upon the box 34 at one end. and at the other end are provided with rollera 40, which bear upon the earns 41, carried by a rotating shaft 42: wherein the. cross bar 33 will be depressed at each revolution of said shaft; that is to say, at each delivery of a sheet, or pair of sheets, to th jogger; the return stroke heii'ig act-ompli hed by means of the. springs 36 which also mil to hold the rollers 40 on the rock arms in contact with the cams 4].

Motion is imparted to the. shaft 4).

through gear wheels 43. ll and 45, at one side of the apparatus, (see Fig. L). The gear 45 is attached to a shaft it whi h re ceiv'es motion in suitable mamwr from the main gear train of the printing murhinv.

The shaft. 46 also carries the. cutting cvlinder 19; shaft 42 being geared to shaft. 46. so as to rotate in unison with said cylinder;

The shaft. 46 is also provided with 21 larger gear 47, which meshes with a gear train 45,

49 and 50, (see Fig. 2), to communicate an L of an arm T5 illllltllttl to the shaft 72.

accelerated motion in the same direction to the shaft of roll 23 by means of the gear 51, which meshes with gear 50, the lift. of the roll 23 bein so little as not tothrow these gears 50 1111551 out of mesh.

Motion is imparted to thh perforators and feed rolls through the bevel gear 32, which i driven from the main gear train of the printing machine; said bevel gear being at.- tached to the shaft. of the under perioratin roll 6, and having attached to its outer emf. which projects beyond the opposite frameplate. the ear 53, which meshes with gear 34 attach to the snat't wliirh carries the perforate! segment 7. An idle wheel 55 transmits motion from gear 5 3 to the gears 56 and 57. which transmit motion to the upper perforator. From gear 56 motion is imparted to the feed roll through the idler 5S and the gear 51'). the upper roll 3 being held in frictional contact with the roll 4. in the usual. manner. by spring artuatod l ournal blot-As slidabiy mounted in the frameplates. From the idler motion i transmitted to the lower rolls through the gear 60.

For the purpose. of rai ing the upper roll 3 and 3, to permit the adjustment of the webs. in alining their printed matt r. I extend the roller shafts, and provide. them with the knobs 61. In order to get at the under perforator ,or adjustment. etc" I make the apron 14. removable. said apron being hehl in place by a clamping bar 62. mounted upon the end of the rod 63, which passes out through one of the frame-plates.

The jogging merhauisni consists of a transversely movable plate (34. carried by rock arms 63, at one side: of the jogging box, said rock arms ()5 being actuated by the reciprocating bar (37. mounted in bearings (38 on the delivery table. and actuated in one .lireclion by the spring {22 the tension of whieh is adjusted by the sleeve T0. adjustably mounted on the ro=i GT. 'lhe outward motion of the rod (J is imparted thereto by means of an arm 71. mounted upon an oer-illating shaft 71!. actuated by the arm 73. whit-h contacts with a ram on the shaft of uylint'ivr H. .\n end jogger i'S, (see. Fig. 3.), is carried by a rod T mounted in bean ings YT on the delivery table and actuated by spring 79. which presses upon the adjustable collar 81). in one direction; in the opposite din-Minn being avtuatcd by means This gging m-w-hanism is not. essentiallv new. and is \l'\-"l'll)(tl sharply to; the purpose of illustrating the compl te operation of the apparatus.

At their outwartlmnlsthe sheets are held in almement during the jogging operation bv means of :1 plate 5] hin ed to the bottom of the-slop 52, again t w llt'll the sheets are brought. to rest as they 'are delivered from rolls 33. 24, upon the ledges 30. The stop I jogger of the next succeeding sheets. In

it held in position lit a bent arm 83, nimng g F ig. 3.4he pressor arms 31 are shown as havirom one -a.de of the jogging hox. The rod ing-mmmenced their downward stroke, roller 85 prevents'the leaves of a steak 'fnom fiy'mg 6 upwlrd when discharged from the flogging box. The packets of sheets when they reach theroqnired number, are thrown out of the, jogging box h! a aeciprocaung comprising 4m arm 185. adapted to up through a longitudinal hlot in the .hvery table-3nd pivotally mounted in a nliile'BB. cnrried'hy guides $7 positioned below the delivery tzthle. Motion is imported to the slide by lllfihTi-Uf the link -88. and a Iookntrm89,-the-latter-ining: actuated at the proper periods to throw the slide backward and forward in the guides. Upon its backwatt throw the arm strikes a err; -ar 90, and is thereby 'thrown upward into the slot in the delivery table. being fastened in upright position by a deli-m 91. so that on the mut'ward throw of the slide it will push the packet of sheets outward from .the ing box. the plate 81 being swung ohtwa l v as 'the sheets ass beneath it. when the slide has reach its extreme outward throw. the detent 91 is actuated by a cam surface 92 to release the arm whirl: is then depressed for the return throw. This disnhnrging .drvice is not ffilllltlll) new. and I lay no claim to it heroin. After being illfitlifilgtd from the jogger. the packetfi nmy :he at Ulti'tf removed by the opcmtor. or carried l1 #uimhle meolmnifln to u still further point of delivery.

The-operation of the npparutue in as follows:l\fhere two webs A. and ll me o he run thmugil the printing mar-hine. they will discharge lirat be properly adjusted into \erti 'al and longitudinal nlinement. so that the printed or other matter on one sheet will fall di- Q l e-(fly above that on the sheet below. when the wells arrive at the cutting mechanism.

When no adjusted. the webs. wh n the machine is-in motion. will pass from the z'eed rollers'il. 4. and 3. l. to the perforations. 5 where the will receive the 1x*i'f:r2|tton in E the proper localities, the ends of the sheet. after pa$ ing the pcrforntors: and, in fact. while passing through the pcrforntors. being entirely free from any pulling strains,

as the rollers 23 and 24 are held apzlrt while the webs are being fed to the outta-nos will be seen from an inspection of Fig. 3. Immediately after the rotating blade '20 has aseed the stationary blade 17, however. the roll 23 will he dropped upon roll 24. and

thereafter the severed sheets will be delivered with a reatly accelerated motion upon the ledges 30 of the jogging box; thereby carrying said severed sheets to the jogging box sufiicienlly in advance of the following sheets to permit the preset arms 31 to have ample time to be depressed and returned to their upper positions before the delivery to the 40 being shown in the act of riding out on th cam 41. An inspection of theram ll will --'l1ow that this depression and return of the presser arms will he nocomplhhed during one-half of a revoltuioz: of the shaft 42. and. 'tlu-rcfore. during half. the period in which the shee are being delivered to the nutter hladm. By means, if-these horizontal 'uetncullv reciprovnting press-er arms, th sheets or acted upon throughout their entire length to an 'equal degree and at the same time. and an :u'curate and effective delivery into the jogging hox i accomplished. This delivery mechanism will he found particularly adapted for n'mchines running at high speed. \l'hilc l have spoken of thew: prexser arms as being horizontal and vertically recipror-ating. it will he understood that lhave done so because the delivery table. a the jogging box, is horizontal in the apparatus :is illustrated. Should the delivery box he set 1 at an incline. then the presser arms and their direction of travel will he correspondingly tilted. In other words. the presscr urn must set parallel to the surface of the sheets as delivered to the box and reciprocate in that position.

By reason of providing the perforating ylinder with mean: for withdrawing the perforating blades from engagement with the we ls on the pa, between [he v vlindn-r-. l mu elmliled to let the wel; run free to the muting mechanism. thereby avoiding putting n tr=1in upon the webs after they have ht-cn weakened lr the pcrforution.-.. as where roll: are empl yed to draw the web: from the fwlffll'illul'n. The upper-am: may be provided with hut one of these perforators where one web i.- to he upended-upon. or where the perforations on two or m re wells permit them .to he run through the one pel'lol'ntor. and more than two perforators may lie employed where u larger number of we! having difierently nlined perforations are-tulle brought together at the cutting and delivery mechanisms. in making triplicate copy hooks, and the like. Various other deltlllS in the structural features may be changed without departing from the spirit of my invention.
